1 When the watch stops completely, a few swings will start the
second hand moving at two-second intervals.
2 Swing the watch approximately 100 times. There will be about 12
hours of power reserve available.
* It is recommended that the watch be swung further until one day of power
is reserved. As a guideline of recharging, an additional 200 swings, about
300 swings in total, will reserve one day of power.
* If the watch is swung 200 to 250 times, about one day of power will be
newly accumulated.
3 Wear the watch on your wrist.
